Application filed September 22, 1914. Serial No. 862,954.

To all whom it may concern Be it known that I, MORRIS HARRISON, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Spanner Attachments for Hose Couplings and Connections, of which the following is a specification.-

The invention has for an object to provide a connection for hose, of the type ,now customarily employed on fire hose requiring atpresent a spanner to tighten and loosen.

The invention obviates the necessity for the use of the separate spanner tool, enables the rapid attachment and detachment of hose sections without the delay involved in the use of the spanner, and yet permits the use of connections operating the same as those now used.

It is a particular object to provide means for converting the ordinary coupling already in use into a device operable without the spanner.

A further purpose is to enable the manufacture of the device economically and en able its application to use with facility and simplicity.

Another aim is to give a construction which will be durable and liable in a minimum degree to derangement.

Additional objects, advantages and features of invention will appear from the con-n struction, arrangement and combination ofparts hereinafter set forth and shown in the drawings, in which Figure 1 is a perspective view of one embodiment of my invention, Fig. 1 is a detail of a modification of the attaching means,

where the device is made separate from the coupling, Fig. 2 is an end view thereof, Fig. 3 is a detail of a detent for the lever, Fig. is a side view of another form, partly in section Fig. 5 is a cross section thereof, Fig. 6 is a side view partly in section of the device shown in Fig. 1.

There is illustrated in Figs. 1, 2, 3, and 6, a device applicable alike to the male and female member of the ordinary hose connections, and also to plug caps and reducer con nections therefor-particularly desirable for use on the plug devices. In Fig. 1, the ordinary cap 11 is shown, while in Figs. 2 and 6 a reducer 12 is illustrated. My invention in the present form includes an annulus 13 of suitable metal adapted to engage snugly over the cap or other connection, and having a suitable number of lugs 14; on its inner side spaced to engage the usual notches in the cap and connections,'or,- as in Fig. 1 when trunnions 1 5 areprovlded on the cap or connectlon 11, suitable notches 16 may be formed in the side of the annulus'to receive them.

The annulus is also provided with a suitable number. of circumferentia'lly spaced screws 17 engaged 'therethrough and having pointed inner ends to be embedded in themetal of the member engaged within the annulus.v

The annulus isv formed withan extension or lug 18 atone point on" the outer side, from which there project transversely of the major plane of the annulus two ears'19suitably aperturedto receive a pintle 20 carrying the lever 21 between the ears. The lever has its base 'portion curved to lie concentric with the annulus when at the inner limit ofits movement, the curvedpart of the lever beginning immediately adjacent the ears'19. The outer part of' the lever is extended rectilinea-rly a short distance beyond the curve,

which includes an arc of 90 degrees. The- 5 held at opposite limits of its movement yieldably to a certain degree of pressure. With the lever at the outer limit of its movement as dotted in Figs. 2 and 6, it may be grasped to rotate a cap or thelike engaged within the annulus 13, for loosening or tightening, and when not in use may be folded to be close to the connection or the hose'running,

manipulating device as follows: An annu lus 30 is provided, similar to annulus 13 before described, and having the securing screws 17 and lugs 14 or recesses 16 as required. Radial cars 31 are formed integrally on the annulus and intermediately of the ears a lateral extension 32 close to their bases, on

to the first flattened face, as at 38. The

pressure of the spring 33 will thus hold the lever yieldably in closed or open position. he length of the lever should be about five inches,- which will enable the application of suiiicient force in tightening the connection Q1: loosening it, and will also not interfere with the convenient handling of hose equipped therewith.

While I have shown an attachment for ordinary hose couplings it will be apparent that in the manufacture of couplings the annuli 13 and may comprise an integral part or the cap, reducer and coupling membersthat is to say, the connections for the levermay be formed directly on the rotating part orthe coupling. By the use of a breechblock thread in the couplings, the use of my invention would be further desirably enhanced. It is not believed necessary to illustrate this detail which is familiar enough to be understood Without detailed showing or explanation, p #In the use of my inventlon, the plug caps and reducers with the levers carried thereon may be inclosed in the plug covers where Copies of. this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

In coupling hose sections,

In the emergencies encountered in fire departments, Where a minutes time lost may mean thousands of dollars in damage, the provision of a connection with self contained lever of this character is of the utmost value, and it will be obvious that the incorporation of the invention may be attained in a practical and inexpensive manner.

What is claimed:

1. A coupling device including a rotating element, a. leven carried pivotally thereby for movement to position at right angles to the axis of the device at times and to lie closely thereagainst at other times, and vieldable means engaged with the lever to hold it at the inner limit of its movement.

A coupling device comprisinga rotating element, radial ears carried thereby spaced circumferentially, a lever pivoted between the ears, and a resilient member carried between the ears and bearing against the lever, the lever being movable to lie close against a concentric member engaged with the rotating element. I

In a device of the class-described an annulus, a plurality of binding screws engaged therethrough for the purpose described, two circumferentially spaced ears formed on the annulus, a lever pivoted at its base therebetween, movable and shaped to lie close beside a'concentric member connected. to the annulus, and means to hold th lever relea'sably at the inner limit of its" movement.

In testimony whereof I atHX my signature in presence of a witness.
